Reaction Steps

To a solution of 42 (900 mg, 3 mmol) in EtOH (10 mL) was added hydroxylamine hydrochloride (1.0 g, 15 mmol) and pyridine (1.0 mL). After the reaction mixture was stirred at 70° C. overnight, the solvent was removed in vacuo to afford 800 mg (85%) of 1-tosyl-1H-indole-4-carbaldehyde oxime (44) as white solid: MS (ESI) m/z=315 [M+1]+.
